Abstract
The invention relates to the field of steel wire ropes and discloses a steel rope, which comprises a plurality of rope strands, wherein each rope strand is formed by twisting a plurality of steel wires and comprises 16 outer rope strands and 19 inner rope strands, and the outer rope strands cover the inner rope strands; among the 19 inner rope strands, twelve strands, six strands and one strand are respectively distributed from outside to inside; each rope strand is formed by compacting nine steel wires and is hammered during twisting; the cross section of each outer rope strand is fan-shaped, and the cross section of each inner rope strand is irregular in shape; and all rope stands undergo surface contact. According to the steel rope disclosed by the invention, the breaking force of the steel rope is improved by 15% relative to the basis of that of the general steel rope, the tensile strength of the steel rope is improved, meanwhile, the compactness among all the rope strands is improved, and thus, the steel rope is tighter and more wear-resistant, and is prolonged in service cycle.
Description
Technical field
The present invention relates to a kind of steel wire rope, relate in particular to steel cable.
Background technology
Steel wire rope is the very large a kind of consumable material of use amount in producing, living, directly affect efficient and the safety of production, life the service life of steel wire rope, the steel wire rope of general technology twisting shows not wear-resisting performance under the conditions such as vertical shaft hoisting, in use procedure, therefore the phenomenon of fracture of wire in advance can be arranged, fracture of wire quantity transfinites and need scrap more.
Also there is structural unstable defective in the general structure steel wire rope, and rope strand is circular, and is tangent to each other between rope strand, space between rope strand is larger, inevitably there are gravitation and friction between the steel wire of internal layer rope, reduced the compactedness between each strand, greatly affected the life-span of steel wire rope.
The general structure steel wire rope also can be low because of the density metal coefficient, breaking force of rope is little, have a strong impact on its use, have to strengthen the diameter of steel wire rope, or the tensile strength of raising steel wire rope, but these measures will be subject to the restriction of equipment volume and Wire Rope Production factor, and these measures are subject to again existing producing technique of steel cable and restrict possibly.
Summary of the invention
In order to solve the problem of above-mentioned existence, the object of the present invention is to provide a kind of tight, wear-resisting, steel cable that rupture pull force is large.
To achieve these goals, the present invention is by the following technical solutions:
Steel cable, comprise some strand thighs, described rope strand is formed by some steel wire twisteds, wherein said rope strand comprises outer layer strands and internal layer rope strand, outer layer strands coats the internal layer rope strand, and wherein said outer layer strands comprises 16 strands, and described internal layer rope strand comprises 19 strands, per share rope strand is all formed by 9 steel wire compactings, and described internal layer rope strand and outer layer strands forge after compacting when twisted.
after the present invention adopts the appeal scheme, steel wire rope is forged twisted by 35 strand thighs to be formed, outer 16 strands, 19 strands of internal layers, and per sharely formed by 7 steel wire compactings, internal layer rope strand and outer layer strands when twisted through forging, pass through technique scheme, the rupture pull force of steel wire rope has been improved more than 15% on the basis of general steel wire rope, increased the tensile strength of steel wire rope, extended the service life of steel wire rope, gravitation and friction between the internal layer rope strand have been eliminated simultaneously, increased the compactedness between each rope strand, make steel wire rope tightr, wear-resisting, improved the performance of steel wire rope.
Description of drawings
Fig. 1 is the structural representation of steel cable of the present invention.
The specific embodiment
Explanation that the present invention is described in further detail below in conjunction with drawings and the specific embodiments.
As shown in Figure 1, steel cable comprises some strand thighs, and described rope strand is formed by some steel wire twisteds, and wherein said rope strand comprises outer layer strands 1 and internal layer rope strand 2; Wherein said outer layer strands 1 is 16 strands, and internal layer rope strand 2 is 19 strands, and the distribution ecto-entad of described 19 strands of internal layer rope strands 2 is respectively 12 strands, 6 strands and 1 strand.
Wherein said per share rope strand is formed by 9 steel wire compactings, and internal layer rope strand 1 and outer layer strands 2 forge after compacting when twisted; By adopting the appeal scheme, the rupture pull force of steel wire rope has been improved more than 25% on the basis of general steel wire rope, increased the tensile strength of steel wire rope, extended the service life of steel wire rope.
Steel wire rope forges after compacting in the process of twisted, make the steel wire distortion, it is large that abutted surface between steel wire and steel wire becomes, gap smaller, the outer layer strands cross section is fan-shaped, internal layer rope strand cross section is irregularly shaped, be face contact closely between each rope strand, increased between each rope strand compactedness, make steel wire rope tightr, wear-resisting, eliminated simultaneously gravitation and friction between the internal layer rope strand, improve the rotatory of steel wire rope in the course of work, be difficult for distortion, improved performance and the life cycle of steel wire rope.
In sum, the present invention forges twisted with steel wire rope by 35 strand thigh compactings and forms, outer 16 strands, 19 strands of internal layers, and per sharely formed by 9 steel wire compactings, the rupture pull force of steel wire rope has been improved more than 15% on the basis of general steel wire rope, increased the tensile strength of steel wire rope, eliminated simultaneously gravitation and friction between the internal layer rope strand, increased between each rope strand compactedness, make steel wire rope tightr, wear-resisting, improved performance and the life cycle of steel wire rope.Be widely used in the equipment such as vertical shaft hoisting, large-scale lifting salvaging and the tower lifting in harbour, successful.
Tight, wear-resisting, the characteristics that broken pulling force is large, be difficult for distortion of breaking that the present invention has have good economic benefit and social benefit.
Above-described is only optimal way of the present invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some distortion and improvement, within these also should be considered as protection scope of the present invention.
